Chemical material standard laboratory vibrating sifter is a screening equipment dedicated to experimental analysis and particle size detection of chemical raw materials. It is suitable for fine grading of the particle size of powdered, granular or crystalline chemical materials. Chemical materials have the characteristics of diverse types, large particle size span, easy to absorb moisture or easy to adhere. Therefore, the screening process has high requirements for screen specifications, vibration mode and screening accuracy.

 

The equipment is usually equipped with a standard screen frame with a diameter of Φ200mm or Φ100mm, which can be stacked 1 to 8 layers. The screen aperture ranges from 20 microns to 2 mm. It provides stable screening through electromagnetic or eccentric vibration devices, which helps the material to be fully dispersed and screened on the screen surface. By adjusting the screening time and amplitude, the screening error caused by powder agglomeration or static electricity can be effectively avoided.

Classification of standard laboratory vibrating sifters for chemical materials

In the application of standard laboratory vibrating sifters for chemical materials, the screen type is a key factor affecting the screening accuracy and efficiency. According to the manufacturing process and structural characteristics of the screen, it can be divided into woven mesh screen, punched plate screen and electroformed screen

① Woven mesh screen: woven by metal wire (such as stainless steel wire, copper wire) or non-metallic wire (such as nylon wire), and square, rectangular or special-shaped screen holes are formed by crossing the longitude and latitude lines

Features: The screen hole size range is wide (usually 0.025mm to several millimeters), suitable for powders, particles and chemical materials with low viscosity

② Punched plate screen: Punch out round, square or strip holes on metal plates (such as stainless steel plates, aluminum plates), the hole wall is perpendicular to the plate surface, the screen hole has high precision and strong rigidity

Features: Suitable for processing large particles, high hardness or strong impact chemical materials, suitable for coarse-grained materials, high-hardness particles and high-temperature environment materials

③ Electroformed screen: Metal is deposited on a conductive substrate through the electroforming process to form a precision screen, and the screen hole size can be accurate to the micron level (such as 5μm-1mm)

Features: The screen hole size accuracy is extremely high (error ±1%), suitable for screening of nano- to micron-level fine chemical materials and special-shaped particles, such as needle-shaped crystals and flake pigments

Screen type	Typical aperture range	Applicable material characteristics	Chemical application scenarios	Cost comparison
Woven mesh screen	0.025mm-several millimeters	Medium particle size, low hardness, non-corrosive	Paint fillers, plastic particles, conventional powder detection	Low
Perforated plate screen	3mm-50mm	Large particles, high hardness, high temperature or impact	Ore coarse screening, ceramic raw materials, metal powder classification	Medium
Electroforming screen	5μm-1mm	Nano/micron level, high purity, fine classification	Catalyst, electronic grade powder, pharmaceutical raw material detection	High

What are the advantages of chemical material standard laboratory vibrating sifter

Chemical materials have complex compositions and different characteristics. The screening process often faces problems such as uneven particle size, easy agglomeration, and corrosion equipment. The chemical material standard laboratory vibrating sifter adopts adjustable vibration parameters, such as the number of vibrations, the number of rotations and the amplitude, which can be precisely adjusted according to the material characteristics. 

For example, for nano-scale catalyst powders that are easy to agglomerate, high-frequency and low-amplitude vibration can be used to achieve dispersed screening; the multi-layer screen design can complete multiple particle size classifications at one time, solving the problem of large particle size span of chemical materials. In addition, some vibrating screens are equipped with explosion-proof and anti-corrosion materials (such as stainless steel screen bodies), which can safely handle flammable, explosive or corrosive materials to avoid safety hazards and equipment damage.

In practical applications, the chemical material standard laboratory vibrating sifter relies on high-precision screens and stable operation to ensure reliable screening results. For example, the electroformed screen can achieve micron-level screening to meet the particle size detection requirements of fine chemical materials; the elasticity and self-cleaning ability of the woven mesh screen can reduce material blockage and improve screening efficiency. 

At the same time, automation functions (such as timed start and stop, data recording) can reduce manual errors, improve detection efficiency, provide key technical support for chemical material research and development, production and quality control, and ensure the stability and consistency of chemical products.

What can the chemical material standard laboratory vibrating sifter be used for

The chemical material standard laboratory vibrating sifter can be used in a variety of chemical material research and testing scenarios. In the production and development of coatings, pigment powders such as titanium dioxide are screened to ensure uniform particle size and avoid problems such as agglomeration and uneven coating of coatings due to excessively large particles; in the rubber industry, reinforcing agents such as carbon black and white carbon black can be screened to ensure the mechanical properties and wear resistance of rubber products.

For the plastics industry, plastic granular raw materials can be screened to remove unqualified large particles or agglomerated materials, and improve the molding quality and appearance quality of plastic products; in the field of fine chemicals, catalysts, additives and other tiny particle chemical materials are accurately graded to ensure their activity and dispersibility in chemical reactions. For example, the particle size control of molecular sieve catalysts directly affects the catalytic efficiency.
